Diet • Many crabs are omnivores which eat plants and meat like a person. Others are carnivores, like lions, which only eat meat. Some of them are herbivores,like cows, which eat plants only. • Crabs are 10-legged animals that walk sideways. They walk sideways because that’s the way their legs are.

They have enlarged, modified cavities that act like lungs. 3 Reproduction • Crabs may take up to 18 months to reach maturity, depending on the water temperature and the length of the season.
